[Serviced] Rare Vintage 1970 Seiko Bell-Matic Automatic Alarm 17 Jewels 4006-6010 * DIAL (ORIGINAL): Ref. 7010T AD * CROWN (ORIGINAL) * CASE SIZE: 39mm. This recently serviced Vintage January 1970 Seiko Bell-Matic Ref. 4006-6010 is a classic example of Seiko’s mechanical ingenuity, featuring the brand's iconic automatic movement equipped with a built-in mechanical alarm. Powered by the reliable 17-jewel Caliber 4006A, this timepiece belongs to the sought-after "Waterproof" era, produced just before Seiko transitioned to "Water Resistant" markings in 1971. Having undergone a professional service, the watch runs accurately and the signature mechanical alarm rings with a crisp, clear tone. The highlight of this piece is its stunning silver sunburst dial (Ref. 7010T AD), which remains 100% original with sharp applied indices and a beautifully preserved inner alarm bezel. The original crown and pusher operate smoothly, allowing for effortless setting of the time, date, and alarm functions. The stainless steel case (Ref. 6010) retains its strong original lines and characteristic lugs, preserving the vintage geometry that collectors value. The caseback is correctly stamped 4006-6010 with a serial number dating its production to January 1970, confirming its early Japanese provenance. While the 7010 dial in a 6010 case is a unique configuration often seen in vintage Seiko's long history, every component remains authentic Seiko Bell-Matic. Finding a Bell-Matic in such clean, serviced condition with an untouched original dial is becoming increasingly difficult. This piece combines historical significance with everyday wearability, making it a compelling and highly collectible addition to any serious vintage Seiko collection.
